The author of the new biography of Joe Paterno says the late Penn State coach and his family never tried to limit his access to them after the Jerry Sandusky scandal broke.

Joe Posnanski tells The Associated Press none of the Paternos ever tried to influence what he wrote. He said they told him only to write the truth the as best he could.

"Paterno" was released Tuesday.

Posnanski began the project well before Sandusky, Paterno's longtime assistant coach, was charged with sexually abusing boys.

He had extensive access to Paterno before and after the scandal, which led to Paterno's firing by Penn State. Posnanski says Paterno's five children wanted the truth to come out so "people would see their father for what he was."
